My invention relates to an improved method of producing box or carton blanks, and also to the resulting box or carton.

An object of my invention is to economically produce box or carton blanks of improved appearance and flnish.

An object of my invention is to produce box or carton blanks, bearing printed matter on opposing faces, in a manner whereby substantially l0 absolute register of the printed matter is obtained. Usually, such printed matter includes marginal or other outlineimpressions as well as advertising and other printed impressions, my invention attaining register of such marginal or other outline impressions as well as aligned and positioned relationship of the advertising and other printed impressions relative to the configuration of the box or carton when set up.

My invention is applicable to boxes or cartons formed from integral stock.

My invention is particularly applicable to boxes and cartons embodying a fly leaf which is integral with the body of the blank.

In carrying out my invention, the printed matter is impressed in such number of varied colors and other impressions as may be desired to provide impressions on opposing faces of the box or carton. as well as upon the fly leaf, if so desired. The printed matter, inclusive of the maximum number of desired colors and/or other impres-, sions pursuant to the preferred forms of my invention, are applied upon but one face of the web.

More specifically, a preferred form of my process comprises the feeding of a web through a suitable printing machine c apable of impressing the desired printed matter in the desired number. of colors upon one face of the web, the width of the web being substantially twice that of the final blank, inclusive of the fly leaf, if any, the resulting single face imprinted web being then suitably folded upon itself, accompanied by the application of adhesive to bind the nonimpressed faces of the web to one another as a composite web, and then blanking out such composite web in accordance with the outline of the desired boxor carton, the resultant blank being the box or carton in flat or collapsed status.

Another embodiment of my invention provides an insert ply of cardboard or relatively inexpensive, and therefore unfinished, sheet material which may also be in web form, the imprinted web being applied upon opposing faces of such insert ply.

The most preferred form of my invention, as

'(ci. ss-asm to process, comprises the step of folding the printed web oppositely upon itself at both sides, to thereby locate the original side edges of the web within the resulting side edges of the folded web, the original side edges advantageously being located along a line of longitudinal folding or scoring. Accordingly, boxes and cartons and the like thus produced by my process possess the further distinctive advantage that the edges located at; the thus oppositely folded web are "rounded and finished as distinguished from severed, and thereforeunflnished, edges. Such most preferred form of my invention is especially advantageous in the production of boxes or cartons embodying a fly leaf at one or both sides of the box or carton blank, the original impressed web being in width substantially twice .that of the resulting box or carton blank.

- My invention also affords the control of the flexibility of a multiple ply by proper selection of the bonding medium for bonding the folded web, either directly at its folded reverse face or upon opposite faces of an insert ply, such flexibility control being had, as for example, by adding glycerine or other ingredient of proper viscosity to the glue or other bonding medium. The resulting multiple ply, embodying such glycerlne or equivalent in the residue bonding medium, possesses a degree of flexibility controlled by the proper selection and proper proportion of the flexibility-controlling ingredient of the bonding medium.

Further features and objects of the invention will be more fully understood from thefollowing detail description and the accompanying drawings, in which Fig. l is aside elevation,largelydiagrammatic, illustrating the step of passing aweb of the material to be impressed through the indicated printing stage. This view also indicates the supplemental stage of scoring the web lengthwise to faciliate the later operation of folding the web.

Fig. 2 is a detail view, on an enlarged scale; in plan of a portion of the impressed and scored web derived by the steps indicated in Fig. 1.

Fig. 3 is a detail vertical transverse section on line 3--3 of. Fig, 2.

Fig. 4 is a side elevation, illustrating the stepof folding the impressed web upon itself.

Fig. 5 is a transverse vertical section of the blank resulting upon folding the impressed web on opposite faces of an insert ply.

Fig. 6 is a top plan view, largely diagrammatic, showing an impressed web folded pursuant to either Fig. 4 or 5, in transit to and at the stage of blanking out the folded web to form individual boxes or cartons. This view also includes a diedout box or carton blank having a fly leaf at one side and a fold-in flap at the opposite side.

Fig. 'l is a side elevation of Fig. 6.

Fig. 8 is a transverse vertical section of an impressed web folded at a single, i. e., middle, line of scoring directly upon itself, that is, without an insert ply.

Fig. 9 is a vertical elevation, largely diagrammatic, viewed from a position opposite to that of Fig. 4, showing the stage of passing the insert material through an adhesive bath and the subsequent step of applying the impressed web or; opposite faces of the adhesive coated insert D y- Fig. 10 is a detail transverse section on line llll of Figs. 4 and 6.

Fig. 11 is a plan view of a box or carton blank having a fly leaf at one side of the blank.

Fig. 12 is a detail transverse section on line I l2l2 of Fig. 11.

Fig. 1 generally indicates at ill the web to be printed or otherwise impressed, preferably supplied from a roll I I. At I2 is represented a regulation multi-color printing machine, applicable for multi-color printing and/or other multiple impressions. At It is diagrammatically indicated any suitable scoring device, for scoring the web longitudinally to facilitate the subsequent operation of folding the impressed web upon itself at such scoring.

As to details appearing in Fig. 1, the roll ll of web material is shown supported in a regulation bracket ll; at I! is indicated a regulation feedin roll device. At l6, l1, l8 and I9, etc. are indicated color printing and/or other impression units for applying the desired number of colored or other impressions. The stated device I3 is employed jointly as the feed-out roller mechanism as well as to score the web as above set forth.

At Illa, see Fig. 1 and Fig. 2, is indicated the impressed web, bearing the desired impressions, in this instance, see impressions. 20, see Fig. 2, applicable to a box or carton for packaging and displaying chewing gum. At lllc, llle, are indicated two longitudinal lines of scoring, each of which may, as shown, (see Fig. 3), crimp the web lfla. in direction upwardly relatively to the impressed face of the web. v

As above indicated, the impressed web may be folded and bonded upon its non-impressed faces directly, see Figs. 4 and 8. or upon opposing faces of an insert ply 22, see Fig. 5, which insert ply maybe fed between the folded web Illa and 1 the web Illa bonded at its non-impressed faces to such insert material 22.

The adhesive is applied, see indications 23, 23, Fig. 9, to the opposite faces of the insert material 22, in a suitable manner, as by passing a web of the insert material 22 through a bath of the adhesive. as indicated in Fig. 9, that is, over a roll 5|, thence under the roll 52, submerged in the bath 53 of the adhesive, and discharged between the rolls 54, 5|, which rolls 54, 54, are provided with scrapers 55, 55. Advantageously, the folding and bondingof the impressed web Illa is had by a succession of pairs of pressure rolls, see 26, 24, 25, 25, Figs. 4, 9. and 6.

The resulting multiple ply web is passed from the stated pressure rolls to suitable blank-scofi ing means and blank-cutting means. As is indicated in Figs. 6 and 7, the blank scoring operation may be eflected by a scoring roll 26 and its cooperating impression roll 28a, and the blank cutting operation may be effected by a cutting roll 21, and its cooperating impression roll 21a.

Typical lines of scoring are indicated by 2!, see Fig. 6. Typical-lines of severing are indicated by 29.

The resulting blanks, see IIIB, Fig. 6 may be stacked as is indicated in Fig. '1, as upon a receding platform ill.

The thickness of the web of the ply insert 22, if employed, is selected with reference to the thickness of the impressed web ID, to derive the desired eventual thickness of the box or carton blank, thus affording economy by proper selection of materials for the respective webs in accordance with the costs of the selected materials.

As appears from the individual box or carton blank, see I 08, Fig. 6, and also from Fig. 11, the edge lllc of the indicated fly leaf Illd is "rounded and also finished, in that the web I0 extends about the stated edge when folded at the score lines We, see also Fig. 2. Obviously the edges resulting from folding at the score lines 28, disposed intermediate the resulting died-out blank, are also rounded'{ and finished. I

The more preferred forms of my invention providefor a rounded and finished edge at llle as well as at the opposite edge llic, namely, by folding the printed web Illa about both of its side edges, the original edges Ill! of the full or single web, see Fig. 2, being ultimately located intermediate, see Illf, Figs. 6 and 10, the edges of the folded-over web. Desirably, but not necessarily, the original edges "I! are located substantially coincident with a scoring line 28. The portion lily of the blank is a fold-in flap.

The parts of the blank shown in Figs. 11 and 12 corresponding to like parts of the blank shown in Figs. 6 and 10 are designated by like reference characters. The blank of Figs. 11 and 12 has a fly leaf "Id at one side, namely, adjacent the edge llld, the edge llle at the opposite side of the blank being an edge of a side of the box or carton, which edge llle is rounded and finished.

In the employment of a web or other stock, folded upon itself and bonded directly at its nonimpressed face, pursuant to my invention, the web or other stock may be coated or otherwise finished on one face'only, upon which finished face the printing or other impressions are applied, thus effecting marked economy in the cost of web or other stock material in that the body of the web or other stock may be selected 01 low cost and further that such web or other stock is of but one-half thickness, and may be paper as distinguished from board, as well as effecting a saving by reason of the single operation of printing or impressing, namely, on one face only.

From the above it appears that my process effects positively exact register of all printed and /or other impressed matter appearing ultimately on opposite faces of the parts of the box or carton when set up.

-It will'be observed that the rounded and finished opposite side edges I00 and Hie are spaced from one another and with respect to the die of the desired box or carton blank, to locate such edges "I0 and llle within the contour of the die, that is to say, at the margins of the resulting box or carton.

such insert material, and'further, by reason that such insert material may provide the major thickness of the resulting blank. In contradistinction from my invention, the prior practice of employing a single web of paper board for the eventual box or carton blank, such board is required to be finished on both faces and therefore of relatively high cost. Furthermore, such prior practice requires the printing or other impressions to be applied on its opposite faces, therefore necessitating two separate printing or impressing operations, namely, for each face, and in addition introduces the most difficult, and commercially most expensive problem of seeking register of the printed matter appearing on the opposite faces of the single web or other stock and resulting blank.

lily invention provides further for the control of the degree of flexibility of the resulting multiple ply, whether with or without an insert ply, namely by proper selection and proper proportion of a flexible-imparting ingredient to the bonding medium. For example, glycerine may be added in proper proportion to an animal glue, or vegetable glues or other water solvent glue or other adhesive, whereby upon evaporation of the vaporizable constituent of the resulting bonding medium admixture, the glycerine or equivalent ingredient constitutes a part of the residue, i. e. resultant bonding medium. Similarly, other flexibility-imparting ingredient may be employed with the above stated or other types of glues or other adhesives.

Whereas, I have described my invention by reference to specific forms thereof, it will be understood that manyv changes and modifications may be made without departing from the spirit of the invention.
